signatures: [images.Contrast PERCENTAGE]
toc: true
---
The percentage must be in the range [-100, 100] where 0 has no effect. A value of `-100` produces a solid grey image, and a value of `100` produces an over-contrasted image.
## Usage
Create the filter:
```go-html-template
{{ $filter := images.Contrast -20 }}
```
{{% include "functions/images/_common/apply-image-filter.md" %}}
## Example
{{< img
src="images/examples/zion-national-park.jpg"
alt="Zion National Park"
filter="Contrast"
filterArgs="-20"
example=true
>}}
